Severn was shivering so violently, at first Dakota thought his insulation suit must have ripped too. But it wasn't that.

'Dak . . . Dakota. Listen to me, Dakota.'

He had fallen to his knees, staring at the desolation around them. Dakota was at a loss about what to do next.

The air all about was stained with the acrid fumes of the burning ground transport. Dakota knelt by Severn and put a hand on his shoulder.

'What is it?'

'The angel. Where's it gone?'

'I don't know, Chris. Are you all right?'

'No.' His shivering became worse. He brought his pistol in close to his chest, hugging it there in both hands as if he were cradling a baby. 'Something's wrong, Dakota. Something's really very wrong.'

Dakota tried to deny it at first, but something was was wrong, a sense of unease that had been growing within her for several minutes. At first she couldn't figure out what it was. wrong, a sense of unease that had been growing within her for several minutes. At first she couldn't figure out what it was.

The voices from the Circus Ring came back to harangue and plead with her again. They were getting harder and harder to ignore.

'We'll be fine, Chris. We'll be fine.'

'No. No, we won't. We won't be fine at all.' He looked at the landscape around them, at the devastation, as if seeing it for the first time. 'What just happened here?'

'We were carrying out-'

G.o.d's purpose?

No, that wasn't it. Then what?

Dakota squeezed her eyes shut. Alerts flashed at the edge of her awareness, clamouring for her full attention. She tried to make them go away but they wouldn't-not this time.

Then she became aware that the presence that had filled her all through the crash-landing and beyond was gone now, and with it the ineffable sense of majestic, holy purpose that had filled her. It felt like waking up from the worst nightmare imaginable.

She turned to Chris and opened her mouth to say something but, before she had time to utter so much as a syllable he shoved his pistol in his mouth and pulled the trigger. Dakota screamed as his body was thrown back across the roadside by the force of the shot.

She stumbled and fell to the ground, her fingers clawing the hard road surface, her terrified gasps sounding metallic and hollow inside her breather.

After a while, she regained some control over herself. She was Dakota Merrick, and a machine-head. She was a pilot for the Consortium.

All around her lay the bodies of the dead. Too many of them were children.

She crawled over to Severn. There was still the faint flutter of a pulse, but he'd probably be dead within minutes. Perhaps that was for the best.

She lifted herself up and surveyed the scene more calmly. She then started to walk away from the wrecked ground transport, away from the orbiter, moving in the direction of Port Gabriel.

There were even more plumes of smoke rising from that direction than the last time she looked. Dakota stopped and glanced over at the roadside statue, its hands still thrusting skywards in mute agony. It started to rain.

She remembered everything. She remembered too much.

Twenty-two.

Dakota started to come round again after a couple of minutes. Corso felt her take a firm grip on his shoulder as he hauled her towards a service lift leading to the centre of the gravity wheel and to zero gee.

Dakota mumbled, her words slurred and mashed together. He tensed instinctively, fearing that she might attack him again. After a moment she opened her eyes and focused on his face.

'Corso?'

It was barely a mumble, but he nearly wept with grat.i.tude. Whatever had taken her over previously had relinquished its control-at least for the moment.

'Come on, Dakota.' He dragged her on to the elevator, an open platform used for transferring equipment from the ship's centre to the inner circ.u.mference of the wheel and to the bridge.

The elevator started moving at a painfully slow pace, but Corso felt the gravity drop rapidly away.

Once he had her out of the elevator, however, it was like trying to steer a boulder upstream. He'd kick off from one wall at the extreme end of a drop shaft, pulling Dakota after him, but the problem was in judging their combined momentum. And, just when he thought he had her aimed right, she'd twist within his grasp and send them both sailing towards a side wall.

Then, more often than not, he'd have to try and get between her and the approaching hard surface before she collided and injured herself. A couple of minutes of this manoeuvring left him feeling like he'd been worked over by a couple of seriously p.i.s.sed-off giants with fists made of stone.

Dakota moaned and blinked, apparently becoming more aware of her surroundings.

'Get back,' Dakota mumbled. 'Piri'

'That's right, Dakota. Back to the Piri.' Piri.'

He could have cried with joy when they finally came to the complex of pa.s.sageways and shafts surrounding the cargo bay.

'Corso . . .' Dakota's expression was still hazy and unfocused. 'Wait, I. . .'

'We're almost there.'

Corso was still wearing his pressure suit. Once he'd got them both inside the airlock leading into the bay, he noticed with a start that the air had started cycling out too soon. He panicked, realizing he wouldn't have time to get Dakota into a suit as well before the air pressure dropped to zero.

Then something very strange happened.

In a flash, a black, oil-like substance spread out across Dakota's skin from under her clothes, till it was covering her completely. Even her hair flattened under this tide, the substance bubbling also into her nostrils and spilling deep into her mouth, forming a smooth membrane over her parted lips in barely a moment or two. He let go of her instantly, backing against the far wall of the airlock in horrified fascination as the door leading into the cargo bay swung open.

His first thought was that this oil-like substance that had swallowed Dakota was the alien presence she claimed had taken over the Hyperion: Hyperion: some liquid monstrosity that had been hiding inside her, rather than that insidious presence being the Shoal-member as she had claimed earlier. some liquid monstrosity that had been hiding inside her, rather than that insidious presence being the Shoal-member as she had claimed earlier.

However, Dakota showed no sign of struggling or thrashing around, as surely she must do if either suffocating or experiencing distress. He could see the steady, calm rise and fall of her chest.

Forcing himself to overcome his terror, he gingerly reached out and grabbed the edge of her jerkin. The others would be hunting for them, and it was only a matter of time before they came to investigate the cargo bay once they concluded there was nowhere else to look. He hauled Dakota after him into the vast interior s.p.a.ce and struggled to guide her towards the Piri. Piri.

The Piri's Piri's external airlock automatically cycled open as he dragged and shoved her towards it. external airlock automatically cycled open as he dragged and shoved her towards it.

Once they were safely inside, Corso pulled off the headpiece of his suit and took a moment to recover his breath. His whole body seemed a solid ma.s.s of aches and pains. It was easier to take light, shallow breaths. Gradually, the pain became a little more bearable.

Dakota had drifted away from him, apparently unconscious, finally coming to rest against a fur-lined bulkhead. He watched as the black oil that had coated her flesh receded once more, apparently draining away into whatever hidden receptacle it lurked within.

He looked around for some way to secure her in case she turned violent again. First he guided Dakota into an acceleration couch, wrapping the webbing tight around her supine form. Her skin felt clammy to the touch, but at least she was still breathing normally. Finally he pulled her wrists behind her back and used a piece of loose webbing to bind her.

'Please remove the restraints from Dakota.'

It was the Piri Reis Piri Reis speaking. 'Please comply,' it continued, 'or I will use countermeasures against you.' speaking. 'Please comply,' it continued, 'or I will use countermeasures against you.'

'It's me, Lucas Corso. She's injured. Her Ghost's been compromised.'

He let himself float against one wall and grabbed at another handhold to keep him in place. 'Dakota gave me the necessary access privileges, Piri. Piri. You can accept my commands.' You can accept my commands.'

Dakota mumbled something he couldn't comprehend, and pulled against her restraints.

'Nonetheless, I require the restraints to be removed from the owner of this vessel. Be warned, I am equipped for lethal force.'

'Piri!' he shouted, venting all the frustration and anger he'd put to one side during his long struggle to get Dakota back to the cargo bay. 'Look at the records for the bridge. Look at what happened, he shouted, venting all the frustration and anger he'd put to one side during his long struggle to get Dakota back to the cargo bay. 'Look at the records for the bridge. Look at what happened, I I got her out of there.' got her out of there.'

'I am now initiating countermeasures. Please be warned that-'

'Listen to what I'm saying! Infective routines have been placed in Dakota's Ghost circuits.'

Corso floated towards a programming interface.

'Please do not approach the interface.'

'AW, just trust me. Please.'

It was useless trying to plead with a machine, but Corso couldn't help himself. 'Look inside her and see if I'm wrong.' He reached out to the console and tapped at the screen, which blossomed into life at his touch.

He'd half expected the Piri Piri to zap him immediately like a fly, but nothing happened. Obviously enough of what he was saying got past its security algorithms so as to give it some cause for delay. 'I'm releasing these data-stack signatures from the moment when the to zap him immediately like a fly, but nothing happened. Obviously enough of what he was saying got past its security algorithms so as to give it some cause for delay.

For the sake of his own life, Corso prayed he wasn't.

Several moments pa.s.sed.

'Correlations with the infected signatures are detected,' the Piri Reis Piri Reis replied. 'Please stand by.' replied. 'Please stand by.'

Dakota's head suddenly snapped back as if a powerful electric current had been run through her. Her teeth clenched in an involuntary grimace, and the muscles in her arms and neck stood out like steel cables under the skin.

'Piri!' Dakota began showing all the signs of suffering a major seizure. Dakota began showing all the signs of suffering a major seizure. 'Piri, 'Piri, stop! What are you . . .?' stop! What are you . . .?'

Her eyes looked like they were about to pop right out of her head, and something very like a scream tried to force its way out from between her clenched teeth.

'Remain where you are,' the ship warned him. 'I am currently cleaning invasive routines from Dakota's implants.'

'You're killing killing her.' her.'

'Any physical responses you see are purely the result of nerve shocks generated by the a.n.a.lysis and removal process.'

Corso stepped forward and tried to loosen her straps. Whatever Piri Piri was doing . . . was doing . . .

Something buzzed against his forehead and a moment later Corso found himself floating at the far end of the cabin.

'Please remain where you are,' the Piri Piri stated calmly, 'or the next shot I give you will be lethal.' stated calmly, 'or the next shot I give you will be lethal.'

Thinking of countermeasures, Corso reached up and touched the skin on his forehead and wondered what the ship had hit him with. He looked around just in time to see something tiny and silver dart back into a recess that closed even as he watched.

Dakota's body jerked again, a low animal sound escaping from between her clenched teeth.

'At least let me get her into the f.u.c.king medbox, Piri? Piri?

'Unnecessary.'

With the next shock she received, Dakota began foaming at the mouth. Corso was too sickened to watch, and looked away.

She suddenly uttered a shriek, her body tensing as if a powerful electric current were flowing through it, but then she fell silent and collapsed back against the couch.

Corso stared at her p.r.o.ne form, his mouth dry.

'The process is complete,' the ship suddenly announced.

'And what? How is she?'

'A more thorough a.n.a.lysis is required to determine if there is any brain damage from her recent head injuries. The invasive routines, however, appear to have been destroyed.'

Corso hurriedly pulled Dakota back out of the webbing. She felt like a broken doll in his arms as he clumsily hauled her into the cupboard-sized s.p.a.ce where the coffin-shaped medbox was situated.

He yanked her clothes off and cracked open the medbox's door. It responded instantly by enveloping Dakota's body with slim, pale sensors as he lowered her in. Needles slid under her skin, while other sensors began probing her flesh. He stepped back, momentarily repulsed: the sensors reminded him too much of the things that had extruded from the walls of the derelict.

'Piri, I need you to give me full access to your control systems.' I need you to give me full access to your control systems.'

'This is not permitted.'

'Dammit! Piri, Piri, I-' I-'

'Corso.'

Her voice was weak. He stared down at her hopefully. She wasn't focusing well, but she was looking straight at him. As he watched, a sensor found its way inside a nostril, while others slithered into her mouth and on down her throat. She twisted and choked for a moment, before relaxing again. He reached down and put one hand on her arm. The physical contact seemed to help soothe her.

'Piri,' she gasped, her voice barely coherent past the sensors blocking her throat. 'Full systems access granted for Lucas Corso. Acknowledge.'

'Acknowledged,' came the reply.

'Dakota, I . . .'

A sensor pushed itself into a vein on her arm and her eyes rolled back, the eyelids closing in deep sleep as the medbox's sedatives took effect.
